Different Welding Services Used Widely in Industrial Fabrication
The manufacturing and industry are the foundation of our society. With such, we are able to have high quality living and holds promising future. The manufacturing and industrial sectors on the other hand will not be able to exist without structures, equipment as well as resources that are made by industrial fabrication and as a result, industrial fabrication as we know will not come to life without welding.
Let us look on how welding plays an important role in industrial fabrication and the different kinds of welding services.
SMAW – this is also known as Shielded Metal Arc Welding or sometimes called as stick welding. Here, the stick is referring to the electrode coated in protectant flux. The electrode holder holds the stick firmly in place and the electric arc is attained by making use of alternating or direct current. In return, this is making the electrode melt slowly while also melting the metals that need to be joined.
Apart from that, the flux coating releases gas vapor and the slag forms a protected environment which act as shield to the welded area from any type of contamination.
GTAW – this is referred as Gas Tungsten Arc Welding and like the name suggests, it is using tungsten electrode to be able to produce weld. When compared to SMAW welding, the electrode isn’t consumed throughout the welding process. Instead, the welded area is being protected from atmospheric contamination by inert gas which is typically Helium gas or Argon.
GMAW – referred as Gas Metal Arc Welding, it makes use of consumable wire electrode fed through welding gun. Inert shielding gas such as argon or mixture of carbon dioxide and argon is being sprayed to the welding puddle in order to protect it from contamination.
MIG welding become the most common method of welding in various industrial settings due to its relative ease and versatility. However, if you are going to use it in an area with high air volatility or any outdoor setting, then you may not be able to see its fullest potential.
FCAW – Flux Cored Arc Welding or FCAW has strong similarity with MIG welding but FCAW is using special tubular wire that is then filled with flux. Well, the flux might be enough by itself in protecting the welding puddle from contamination or shielding gas might be used which depends on the filter material as well as other circumstances.
SAW – it means Submerged Arc Welding and uses consumable electrode that’s automatically fed. It is using characteristic blanket of granular fusible flux which consists of various compounds similar to lime, silica, calcium fluoride as well as manganese oxide. In order to protect the welding area, the combination is totally submerged.
